@timeakesmarky you need to have some version of Python3 installed on your system to be able to do this.
Can you tell the output of following command on your machine?

python3 --version

Answer 2 · 2019-09-11T17:03:39.000Z

I have python 3.7 installed but
this command says python3 is not recognized as an internal or external....

Answer 3 · 2019-09-11T17:04:04.000Z

But,
python --version says python 3.7.4

Answer 4 · 2019-09-11T17:46:24.000Z

virtualenv venv --python=python3.7
source venv/bin/activate

This should work for you

Answer 5 · 2019-09-11T17:51:23.000Z

Nope, I already tried that, same error.
The path python3.7 (from --python=python3.7) does not exist

But wareader works even without executing these two commands. So, why do we need these 2 commands?

It is considered to be a good practice to have your Python packages seperated on the basis of your project i.e., each project should have its own dependencies. Here's a good answer explaining the need for virtual environmentns: https://qr.ae/TWKrc1

Can you send me the exact output for python --version command and which python command?

C:\Users\Timea\AppData\Local\Programs\Python\Python37-32\python.exe

Answer 11 · 2019-09-11T18:07:30.000Z

virtualenv venv -p C:\Users\Timea\AppData\Local\Programs\Python\Python37-32\python.exe
source venv/bin/activate

Answer 12 · 2019-09-11T18:11:35.000Z

This works. It also works with,
virtualenv venv --python=python
What if I want a different python version?

source venv/bin/activate doesn't work.

What if I want a different python version?

You would need to install a different version of Python and provide that path in virtualenv venv -p <new_path>

source venv/bin/activate doesn't work.

Can you try .\venv\Scripts\activate

Answer 14 · 2019-09-11T18:26:36.000Z

Oh ok. But why does THIS app need the virtualenv setup?

Activation works now.

Answer 15 · 2019-09-11T18:44:01.000Z

This app in particular doesn't need virtual environment. It is considered a good practice to do it anyways.

Closing the issue since the issue seems to be resolved.
